instead of traditional cement mortar, tile adhesive is used for pasting decorative materials such as tiles
Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymer,
Hydroxypropyl methyl cellulose can be distinguished from its water-holding capacity. The water retention of methyl cellulose ether at high temperature is an important target to distinguish the quality of methyl cellulose ether.
starch ether is usually used in combination with methyl cellulose ether, which shows a good synergistic effect between the two. Adding an appropriate amount of starch ether into methyl cellulose ether can significantly improve the anti-sag and anti-slip p
Due to its low reactivity, the industrial utilization of lignin has been restricted, so the activation of lignin has become the focus of current research. Lignin is difficult to use because of its structure and properties. Lignin is a three-dimensional re
With the rapid development of the construction industry, people's demand for new building materials is also increasing day by day. Due to the increase of people's awareness of environmental protection and the continuous improvement of construction effic
Flocculent lignin fibers are one kind of lignin fibers. They are flocculent or nearly powdery in appearance and white or gray in color. Flocculent lignin fibers are engineering fibers of high quality and purity made of pure flocculent fibers through physi
The price of HPMC cellulose is higher, and the price of CMC cellulose is lower
2) HPMC without any material adverse reaction of cellulose CMC cellulose, because the production of residual acidic substances, used together with ash and cement were not calc
About putty powder easy to powder of the problem, or the strength can not reach what. All know that the putty powder need to add cellulose ether, many users do not redispersible emulsion powder. Many people in order to save costs, without rubber powder, b
Hydroxypropyl methyl cellulose (HPMC) is mainly used to keep the cement in mortar hydrated sufficiently before hardening, so that the cement does not get enough water to solidify because of the rapid loss of water. Only when the hydration reaction of ceme
first look at the whiteness of hydroxypropyl methyl cellulose, the appearance of color is white, uniform color, there is no more black spots under the microscope; poor color slants gray, black spots more. Look at the shape and liquidity of the particles,
In many high-rise building exterior wall construction, often waterproof mortar layer cracks, cracks, hollowing, shedding and other quality problems caused by improper operation. Among many problems, leakage of exterior wall is one of the most urgent probl
For this special chemical term, ordinary people may not be very familiar with the redispersible latex powder is a kind of product, in our life and played a role. Therefore, now related to the main products and product performance, we have a brief introduc
For people who have just come into contact with hydroxypropyl methyl cellulose, it is not clear which fields to use and what kind of hydroxyethyl methyl cellulose. Here is a brief introduction to some common sense used:
Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic, fibrous or powdered solid, which is prepared from alkaline cellulose and ethylene oxide by etherification reaction and belongs to non-ionic soluble cellulose ethers. HEC has bee
How to choose the redispersible latex powder, in general, when making the formula, there is really no way to start, in addition to putting the product into the experiment, there is no effective way. Redispersible latex powder is the process of emulsion re
One of the most important quality properties of redispersible latex powder is redispersibility. That is, when dry-mixed mortar is mixed with water, the degree of dispersion of redispersible latex powder is good or bad. As shown in Figure 1.
Concrete water reducer can be divided into high-efficiency water reducer, air-entraining water reducer, ordinary water reducer and so on. It can reduce the water consumption of concrete, greatly improve mixing efficiency, and also save cement. Let's unde
Daily-grade hydroxypropyl methyl cellulose (HPMC) is a synthetic polymer made from natural cellulose by chemical modification. Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from that of synthetic poly
First, coated kaolin and titanate coupling agent were put into high-speed heating mixer for modification. The optimum technological conditions are as follows: the ratio of modifier to mineral powder is 3:100
The incompatibility between water reducer and air entraining agent shows that the air entraining effect of air entraining agent is affected by the combination of water reducing agent and air entraining agent. It is found that the reason for this phenomeno
According to the "Method for Testing the Strength of Cement Mortar (ISO Method)" (GB/T 17671-1999). Cellulose ether and cement are first fully mixed in the sample bag according to the prescribed poly-ash ratio. After adding the
By rotating method, the cellulose ether samples of specified quality were added to 250 ml glass beaker, then 250 g hot water of about 90 degrees Celsius was added. The cellulose ether was fully stirred with glass rod to form a uniform dispersion system in
